Teacher: Given an English sentence, convert it into the french language.
Teacher: Now, understand the problem? If you are still confused, see the following example:
He later scouted in Europe for the Montreal Canadiens .
Solution: Il a plus tard été dépisteur du Canadiens de Montréal en Europe .
Reason: English sentence is converted to the French language.

Now, solve this instance: This could be done by increasing either the calibre of the weapon and hence the weight of shell , or by lengthening the barrel to increase muzzle velocity .
Student:
Cela peut être fait en augmentant le calibre du canon et donc le poids du projectile , ou en allongeant le canon pour augmenter la vitesse initiale de l' obus .
